Playing Cards
One of the most common questions we get is “What is the
difference between bridge size and poker size playing cards?”
The Difference Is Size!
OK, simple enough. The technical difference is simply the size
of the playing cards. Bridge size playing cards are 2.25″ x
3.5″ (57 by 89 mm) while poker size playing cards are 2.5″ x
3.5″ (64 by 89 mm). That’s really all there is to it. The
decks are the same, both 52 cards with a few Jokers. One set
is just a bit narrower than the other. The reason for the two
sizes is simple as well. When you play bridge, you will be
holding up to 13 cards in your hand. That extra 1/4″ could add
up quickly if you were playing with poker size cards.
Therefore, bridge size playing cards are easier to hold and
play with when you are holding a large number of cards in your
hand.
